Q: 2 siuations: #1 Engine stutters at 3k rpm. #2 Car can barely accelerate and stutters when it does. VSA + Checkengine light flashin

asked by on December 16, 2017

Depending on how my car is feeling when I turn it on, two scenarios occur:

Scenario 1) Car turns on, check engine light is on. Car feels totally fine and I accelerate fine, until it hits 3k RPM. Once it hits that, the engine starts stuttering and it can't accelerate past the 3krpm. As long as i let go of the gas (which drops the rpm) it's fine.

Scenario 2) Turn the car on & check engine light is on and flashing. The VSA light is on and a triangle with a ! is on too. In this scenario, I cannot accelerate at all without the engine stuttering. When the car does the natural coasting of being in drive, it doesn't stutter, but the second I touch the gas pedal, instant stuttering and it can't do anything.

A friend of mine changed the crank shaft sensor and disconnected the battery for an hour and the car had been working for 2 weeks after that. But now I'm having the same issues again.

Check Engine codes: Cylinder misfire 1 & 2 and something about emissions. It changes based on scenario.

My car has 70000 miles.
My car has an automatic transmission.

The causes of the misfiring have to be determined and resolved first. If poor operation remains after the misfiring is resolved, then there might be additional issues. If you are reading Diagnostic Trouble Code P0301 that refers to cylinder no. 1. P0302 refers to misfiring for cylinder no. 2. Among the causes of cylinder misfiring are faulty spark plugs, low compression, damage or excessive wear of spark plug wires and/or coils, faulty fuel injector, clogged EGR valves or tubes, burned valves, improper ignition timing, vacuum leaks, leaking head gasket, faulty camshaft sensor, faulty crankshaft sensor, faulty mass air flow sensor, faulty oxygen sensor, faulty throttle position sensor, faulty catalytic converter, and others.

I have a 2000 suzuki grand vitara v6 5 speed manual transmission rear wheel drive. A couple weeks ago it made a loud clunking noise I stopped because i thought it was my tire. It stopped and then last weekend when i was driving and no matter what gear i was in it was still sounding like i was downshifting. Then yesterday in a parking lot had to stop for someone crossing and when i put it in 1st gear and went to release the clutch my car my the worst noise ever and the clutch wouldnt release and car stalled. Tried again and engine just revved and wouldnt move there was a very loud POP and when i went to push it into a parking spot the car would only go a little bit then stop and wouldnt go any further without making a loud popping sound. What could that be?

I have a 2014 VW Passat, on Thursday the vehicle stopped, overheating. VW dealer collected the vehicle, now I am told the coolant container is full of debri, unable to clean out and if they have to flush the system it will costs over $10,000/. My vehicle has only been serviced by the same VW dealer since purchase and the vehicle has 140,000 miles so the advice is to get a new vehicle as they have never seen this problem. The Thermostat has been changed, but still overheating and the coolant is drained and continues to be full of debri
